Application filed September 19, 1912. Serial No. 721,162.

To all whom it may concern:

Be it known that I, JOSEPH A. BOURKE, a

citizen of theUnited States, residing at Boston, in the county ofSufiolk and State of Massachusetts, have invented certain new and usefulImprovements in Compression- Hydrants; and Ido hereby declare the folafull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates 'tohydrants and more particularlyto firehydrants'of "the compression type.

The object of the invention is to provide an improved closure forthevalve mechanism'and make certain other improvements Fin th'econstruction and arrangement of the "parts of a hydrant of this typecausing a 20 resultant increase-in Leflicien'cy.

W1thth1s ob ect inview, the various features of the invention consist incertain novel of a showing the several 1 is a longitudinal section inelevation "upon the line '2'2 of Fig. 1;Fig. 3 is a detail view showingasection-takenuponthe '=line3r'3'of Fig. 1 ;*-Fig. 4 is a top plan view"of thehydrant with the hood applied there- "to; and Fig. 5 is showingthe hoodsecured in position.

an elevation of the hydrant The illustrated embodiment ofthe invent1onis-shown in connection with a hydrant -ofthetype described in theapplication filed byRourke, April 6, 1912, Serial No. 689,036.

This hydrant is provided with a main valve casing 1,.a stand pipe orbarrel 2 and a head 3 which carries the hose nozzles 4 and the mainvalve operating mechanism. The main valve 5 is rigidly secured to thelower end of a spindle '6 and is'arranged to engage the valve seat 7.The upper end of 'thevalve'spindle isthreaded to engage an operatingnut10 which is journaledin the upper portion of the head and held againstlongitudinal movement relative thereto. The valve spindle is heldagainst rotation and when the operating nut is rotated the Specificationof Letters Patent.

WlllCh is actuated by .21 formed-integral with the the hood is locked inposition PatentedMar. 28, 1916.

spindle is moved axially to open and close the valve. With thisconstruction and ar rangement a substantially unobstructed water way orpassage 12 is provided having a series of diverging passages 13 at itsupper 'end connecting with each of the hose nozzles 4:- In 'order'toequalize the pressure upon opposite sides of the main valve prior toopening the same, a bypass is provided an operating rod 15 having apolygonal operating nut 16 secured to its upper'end.

It is very desirable that the operator "should knowat all timesthe-exact position "of the main valve and to this end an indicatingmember 17 *spindle (land is arranged to move along "the face ofthestandard 18 which is pro- *vided with suitable indications to-showthe position of-the valve. In the illustrated em 'bodiment of the isv-secured to the valve invention this indicating device, as shownclearly in Fig. 3, consists of a pair of metal straps 19 securedtogether at their inner ends adjacent to the valve spindle and havingtheir outer'free ends extended in opposite directions and bent laterallyto position them parallel to the indieating faces ofthe standards. Inaddition, proper indicating characters are applied to the spindles forcontrolling both the main -valve and'the hose nozzles to show the properdirection which the spindle should turn to open or close the valve.

It is verydesirable in hydrants of this type that a simple and eflicientclosure shall e provided to entirely cover and protect the operatingmechanism for the valve and other exposed portions of the hydrant andthat this closure may be firmlysecured in 1 place to prevent tamperingwith the valve when the hydrant isnot in use. To this end a hood 20 isprovided with itslower edge resting at a plurality of points upon aledge head 3. The hood- 20 is provided with a bifurcated foot "22 whichembraces the operating rod 15 and by a lateral projection 23secured tothe rodand extending over the foot when the by-pass is closed,

as described clearly in the application above referred to. In addition,thehood issecurely clamped to the head of the hydrant by a clampingmember 25 which is loosely supported in the upper portion of the hood 20and is arranged to operatively engage with a cooperating clamping ring26 threadedly secured in the standard 18. The clamp.-

inturned flanges 27 having their lower faces tapered and engaged byoutturned feet 28 formed 'upon the clamping member 25, as

shown clearly in Fig. 2. The upper portion of the clamping member isprovided with a polygonal nut 30 to enable the member to be readilyrotated to move the feet 28 beneath the flanges 27 forcing the hoodfirmly upon the head 3. In order to force the hood yieldingly intoengagement with the head 3 and avoid any rattling or chattering of thehood, a flexible washer 31 is interposed between the cooperating facesof the clamping member .and hood. The clamping member is normallyretained in position in the upper portion of the hood, but in order topermit the removal thereof a plurality of recesses 82 are formed in thehood. and arranged to register in one position with the outturned feet28 to allow the clamping member to be removed. When applying the hood itis desirable that means shall be provided for positioning and guidingthe hood properly to not only faciliate the application of the hood butto prevent injury and possible oppositely disposed ribs 35 which engagewith'cooperating guideways formed in guide 7 pieces 36. These guidepieces are provided with extended upper faces located above the nozzlesand if the hood is applied in the wrong position thelower-edge willcontact with the face ofthe guide piece anddo no application of the hoodto the hydrant as injury to the valve. In addition, the provision of theguides serves to facilitate the the operator can readily determine theexact position in which the hood should be placed to fit properly uponthe head.

While it is preferred to employ the specific .main valve, an operatingspindle for the valve, a head, a'pluralityof hose nozzles supported uponthe head, a plurality of guide pieces formed-upon vertical guidewaysformed therein, and a construction and arrangement of parts shown anddescribed, it will be understood thatthis construction and arrangementis not essential except so far as specified in the claims, and maybechanged or modified without departing from the broader features of theinvention.
